I am a painfully light sleeper. I hear everything. Add to this my toddler co sleeps. My toddler is a light sleeper. When he is up, I am up. Up up up.
Covering Sparrow doesn't help. Covering Kokomo doesn't help. Juniper stays quiet until she hears someone else and then it is on.
I've just kind of accepted it.
For the record, I don't mind the morning noise. I mind it at 5:30 and 6am. I just wanted them to hold off an hour or so for the summer.
